The incident that frames the question
Tuesday May 20, late afternoon. Niran lifts his head from his laptop and says, putting a can of soda on the desk: "Computer use, for pushing that mockup onto the site — wouldn't that be faster?"
I answer without turning around: "Ten times the token cost of a normal session. To click three buttons."
Silence. He reopens his editor. Françoise crosses the hallway calling out to nobody in particular: "Right, let's go" — she's talking about something else, but the timing is perfect.
This scene, in variants, I've lived through about thirty times over the last two months. Not on the code, on the dispositif around the code, the toolkit that frames the Claude Code session, that loads context, constrains output, interrupts the run. We talk a lot about prompts and very little about prostheses. Here are the twelve tools that survived sixty days of solo production on a hundred-and-eighteen-thousand-line ERP. Some stayed. One was dropped. One is contested. I counted materially before writing — ls ~/.claude/skills/ returns three files, ls ~/.claude/hooks/ returns six, ls ~/tef-erp/.claude/agents/ returns one. At time of writing, the count holds at twelve.
